| Term | Description |
| port triggering | Port triggering allows multiple computers behind a NAT-enabled router use applications which would normally require port forwarding of the same port to each PC, without manually forwarding ports. Similar functionality may be provided by devices, which can broadcast a port to all PCs on the network. When the router sees a connection from a local PC to an outside server, it opens a temporary port forward to that PC from the internet so servers are able to connect back to that PC on that port. |
